Title: A system for taking backup in a data base
Inventor: LARSSON BO ERIK SETFAN
IPC: G06F11/14
Filed: 1993-12-03
Abstract: For backing up in a distributed real time data base on primary memory in operation, all data in the data base are structured as belonging to one of several logic data bases, a logic data base being able to, but need not extend over several processors. A backup function of a certain logic data base is activated by sending a message to a central backup handler, which has information regarding processors, over which the current backup system extends, and synchronizes the backup function over processor borders. The synchronization includes that local data base handlers are informed that backup will be started and that a new transaction log is being created, in which all transactions having not attained commit state and which shall therefore not be included in the backup are logged. The backup will thereafter only contain changes of transactions in the old transaction log.

Title: Apparatus for converting vibratory motion to electrical energy
Inventor: TIEMANN JEROME JOHNSON
IPC: B61D43/00
Filed: 1995-06-08
Abstract: An apparatus for converting vibratory motion along a predetermined vibration axis to electrical energy comprises an enclosure having first and second opposite walls substantially parallel to one another. A magnet carrier structure in the enclosure also has first and second opposite walls substantially parallel to one another.  A pair of springs suspend the carrier structure in the enclosure so that corresponding first walls and corresponding second walls, respectively, face one another with a predetermined spacing therebetween.  The springs allow reciprocating movement of the carrier structure relative to the enclosure only along the vibration axis in response to the vibratory motion.  Separate magnet sets, each comprising a row of permanent magnets, are attached to a respective outer surface of the first and second walls of the carrier structure for producing a respective magnet flux. Separate coil assembly sets, substantially configured and dimensioned like the magnet rows, are attached to a respective inner surface of the first and second walls of the enclosure and are situated to be magnetically coupled to a corresponding one of the separate magnet sets in order to produce electrical current due to magnetic flux changes whenever the carrier structure and the enclosure move reciprocally with respect to one another along the vibration axis.

Patent CA-2153725-A1 (CA)
Title: Angled pipe clamp
Inventor: ORPILLA SERAFIN W
IPC: F16L3/00
Filed: 1995-08-23
Abstract: Angled pipe clamp is just like any pipe clamp. The only difference is that one end of the angled clamp is higher than the other making the clamp standing at an angle. See figures in sheet 4. The clamp has two legs with a gap between them. Two holes are provided in each leg through which bolts are inserted and tightened with nuts at the other end to reduce the gap and provide stronger grip to the pipe it is supporting. Each leg has its own base with two holes. These are used to fasten the clamp to any surface with a woodscrew or its equivalent. The angled clamp will be used in bath rooms to support shower curtain rods. Ordinary shower curtain rods run straight from wall to wall on the same line as the edge of the the tub. Curtain rod ends are mounted perpendicular to the wall. Because the curtain ends are close to the edge of the bath tub, water spillage from shower on the floor is too much. In a better setup, the curtain rod ends are brought from the outside edge of the tub,deeper into the shower area using 70 degree elbows, with 12 inch radius, see figure in sheet 5. The ends of the elbows are supported with angled clamp. At this condition, the shower curtain encloses the tub many times better than the straight curtain rod, thus reducing, if not totally eliminating, the water spillage to manageable amount.
